A Faraday cage or air gap can’t protect your device data from these two cyberattacks

Two common methods of physical cybersecurity, air gapping and Faraday cages, have been found breachable in two papers released by researchers from Ben-Gurion University.

Faraday cages are grounded cages made of electrically conductive material that can completely block electromagnetic fields and signals. Air-gapped computers are those completely isolated from outside networks and signals. Air-gap setups commonly include Faraday cages.

Anyone who has interacted with a Faraday cage can attest to their effectiveness—put a smartphone in a Faraday cage and you can watch the signal drop instantly. What researchers found, however, is that commonly overlooked low-level magnetic fields can still penetrate air gaps and Faraday cages, allowing attackers to intercept and steal data.
